EXECUTIVE SUMMARY
Deutsche Telekom is piloting TeraStream, an all-IP network Today’s hyper-connected world has not been kind to service that delivers triple-play and other services from the cloud, as providers. The demand for broadband has exploded, as a model for next-generation operator networks. TeraStream customers want always-on connectivity for work and also is a proving ground for software-defined networking play, but don’t want to pay a premium for their growing (SDN) and network functions virtualization (NFV), as bandwidth consumption. In fact, fierce competition among Deutsche Telekom looks to automate and orchestrate cloud traditional telcos, cable operators and mobile operators is services to launch new revenue-generating services and driving average revenue per user (ARPU) lower and lower. adapt to customer needs more quickly. Capturing new market growth, such as over-the-top (OTT) video and cloud services, requires innovation and speed. Deutsche Telekom has partnered with A10 Networks® to Yet many service providers are hampered by the complexity develop a carrier-grade, IPv4-over-IPv6 Softwire solution as a of their networks, which drives up lead time and cost, while virtualized network function, enabling Deutsche Telekom to their more nimble competitors and OTT service providers differentiate and scale cloud services. deliver services that are faster, cheaper and better.
A10 Networks’ software-based and API-driven architecture, Traditional service delivery times, which require weeks commitment to open standards like OpenStack, and a or months to configure using conventional networking willingness to create innovative solutions were key to helping technologies, are no longer competitive. Deutsche Telekom develop what is widely regarded as one of the most innovative service provider networks today.

A NEW NETWORK DESIGN FOR “We designed TeraStream as an architecture that breaks INNOVATION AND AGILITY many of the rules on the operator side,” said Axel Clauberg, Vice President of Aggregation, Transport, IP and Fixed Access at Deutsche Telekom AG. “The attitude of ‘things- Deutsche Telekom is on the vanguard of this change. As were-always-done-this-way’ doesn’t exist here. We a leader in next-generation operator networks, Deutsche questioned all layers and all protocols in today’s network, Telekom is piloting TeraStream, an all-IP cloud-enabled and asked ‘how would you run an efficiently managed network, at Hrvatski Telekom in Croatia. In TeraStream, IP network moving forward?’ We realized that if we truly Deutsche Telekom has re-imagined the network to deliver all wanted to change our cost base, we needed to change services, including voice, IPTV and Internet access, as cloud the model.” services that are provisioned on demand. TeraStream is an open multivendor network, which allows for Deutsche Telekom has taken bold steps to fundamentally greater innovation and avoids vendor lock-in. “It is really key change how it delivers new services faster, at a lower for operators to build a foundation based on an open platform,” cost and with a better user experience. TeraStream is said Clauberg. “We don’t want a dependency on a single an integrated packet-optical network that runs IPv6 in vendor in our critical infrastructure.” the core and is built on an infrastructure cloud model. TeraStream has drastically simplified network architecture TeraStream uses OpenStack for cloud orchestration, and embraces the concepts of software-defined networking allowing it to control the compute, storage and network (SDN) and network functions virtualization (NFV), including resources in its data centers, while empowering customers software appliances, common-off-the-shelf (COTS) to provision resources easily. TeraStream virtualizes hardware, and automated provisioning and network functions so they can be chained together to service orchestration. create customized communications services quickly and as needed.
